IMPROVEMENT IN UPSETTNG TIRES.

To @ZZ whom it may concern:

` Be it known that I, ALBERT STEDMAN, of Homer, in the county of Cortland and State of New York, have invented a new and useful Improvement in Machines for Upsetting or Shortening Tires; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making a part of this speeicatiou, in which a perspective View of said machine is given.

Every blacksmith-shop furnishes a common vise. My object is to furnish an apparatus or machine which may be used in connection or combination with such vise, thus dispensing1 with all that portion ofthe machines in present use which are necessary only in operating them or in applying power. It is constructed of cast or wrought iron as follows: a c are bed-pieces, upon which, at the outer ends,are placed upon the one side toothed or indented projections d d, and upon the other and opposite tosaid projections carnmed levers c c, working upon pivots at g y. Each bed-piece has two arms, b b, extending downward, and each of these hinged to the corresponding arm on the other at e e. The tire being heated at any desired point, is placed upon the bed-pieces c a., and the cammed levers being turned press it against the indented projections d d, and it is thus held securely in position. The ma: chine is then placed in an open vise represented by the dotted lines f f, (the forked arms b b astride of the screw inthe vise.) Now. by

screwing up the vise the bed-pieces a c are brought together, and, of course,I the tire shortened by the distance which such pieces,
